12 Claims. l

This invention relates to printing mechanism and the control thereof for accounting machines particularly of the type shown and described in the following United States patents: to Halcolm Ellis, Nos. 1,197,276 and 1,197,277, dated September 5, 1916, and No, 1,203,863, dated November 7, 1916; to Raymond A. Christian, No. 2,038,717, dated April 28, 1936; and to Paul H. Williams et al., No, 2,189,851, dated February 13, 1940.

More specically, this invention involves the control of printing mechanism for Indian cur rency of pies, annas, and rupees, wherein 12 pies equal 1 anna, and 16 annas equal 1 rupee.

To accumulate these various amounts in the totalizers of machines of the above-mentioned type involved merely the provision of the proper numbers of transfer controls from pies to annas and from annas to rupees. The transfer from pies to annas is accomplished by the use of the usual English transfer from pence to shillings. In other words, whenever 12 pies have been added into the pies denomination totalizer wheel, the transfer means is actuated to cause 1 anna to be added into the annas denomination totalizer wheel. To register the pies, there are provided eleven keys ranging from 1 to 11, which control the setting, or differential movement, of a single rack. Also controlled by this single rack is a type segment having characters 1 to 11 to print the pies as they are registered.

For the registration of annas in the present invention, in order to use standard equipment as far as the racks and the totalizer are concerned, there are provided two rows of keys, two totalizer wheels for annas, and two differential members or racks to actuate their associated totalizer wheels under control of the two banks `or rows of anna keys. One row has keys 1 to 7 and the other row has keys 8 to l5, and the transfer means between the two anna totalizer wheels is effected each time the 1 to 7 wheel has 8 annas added thereto, whereby the 8 to 15 wheel will be moved one step. This 8 to 15 wheel is controlled by the keys 8 to 15 and is moved one step each time any one of said keys 8 to l5 is depressed, because the rack associated with these keys is given one step of movement only under control of any of said keys 8 to l5. The 8 to 15 wheel has 20 teeth and has a IO-point transfer member thereon, so that, each time this 8 to 15 wheel is moved two steps, it effects a transfer into the lowest order rupee wheel of the totalizer.

It can be seen from the above that the totalizer wheels and the racks therefor are standard; that is, the pies wheel and rack are regular English 12- point division members with the regular transfer from pies to annas each time 12 pies have been added into the pies wheel. Moreover, the two anna wheels and racks are the standard decimal or lll-point division members, the 1 to 7 rack and wheel move differentially under control of the 1 to 7 anna keys, and the 8 to 15 rack and wheel are arranged to move one step under control of any of the 8 to 15 keys and one step under control of the transfer from the 1 to 7 wheel each time it passes seven steps of movement, whereby the 8 to 15 wheel, having one step imparted to it by a transfer and one step given to it under control of the 8 to 15 keys, will then transfer l into the lowest order rupee wheel due to the transfer points being arranged for each two steps of movement.

However, to control the printing members associated with the 1 to 7 and 8 to 15 racks necessitated the inclusion of novel mechanism under control of the keys and racks in order to get the proper characters presented to the printing line so that the amounts printed will correspond to the amounts set up on the keyboard. The printing of the pies is simple and standard construction, since the type segment for pies is connected to the pies 12-point rack and is differentially positioned under control oi the pies keys l to 11. The printing of the rupees is standard construction also.

Therefore an object of this invention is the provision of novel means to control the printing of special amounts from an actuating means which controls the addition of such special amounts into regular or standard totalizer wheels.

Another object is the control of the printing of amounts having a special unit base division by means having a diiierent unit base division.

Another object is the novel controlioi the printing of two special denominations of` a monetary system, which control includes special actuating means for the two special type carriers for these special denominations.

A further object of this invention is the novel control of the printing of characters, representing a special denomination, under the joint control of a plurality of banks of keys.

Another object is to control printing from a plurality of printing members under the sole control of either a single one of a plurality of banks of control keys and/or the joint control of all of said banks of keys.

A still further obj-ect of this invention is the control of a plurality of printing members by any key in one bank of keys and certain keys in an- 3 other bank of keys when operated individually and also to control said members by the joint operation of keys of all banks.

Another object is to provide a plurality of banks of control keys, a plurality of associated printin members, means intermediate each bank of keys and its associated member to directly control the latter from its bank of keys, and mechanism controlled by said means to vary the control of the printing members when certain keys are operated in said banks.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, the essen-Y tial elements of which are set forth in appended claims and a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specication.

GENERAL DESCRIPTION Described in general terms, this invention relates to and involves the control of the printing of the annas denomination oi amounts used in the Indian currency.

The particular problem involved was to use as much of a standard machine, of the well-known type of accounting machine shown and described in the previously mentioned patents, for the registration of Indian currency amounts and for the printing of such amounts as they were registered and the printing of totals of such amounts. The printing of the several amounts as they are registered is under control of banks of keys, and the printing of the accumulated totals of such amounts is under control of the totalizers in which such amounts have been accumulated.

In machines of the type above mentioned, the printing members are usually set directy by the adding racks, which in turn are controlled by keys in adding operations and by the totalizers in total-printing operations.

Due to the fact that, in the Indian currency system, 12 pies equal 1 anna and 16 annas equal 1 rupee, there are one bank of keys 1 to 11, one rack, and one totalizer wheel for the pies; and two banks of keys, 1 to 7 and 8 to 15, two racks, and two totalizer wheels for the annas.

The two banks of anna keys and the racks associated therewith are constructed so that depression of an anna key 1 to 7 controls its associated rack to move a number of steps designated by the particular keys depressed, and depression of any one of the anna keys 8 to 15 releases the rack associated therewith to move one step. One step of movement of the rack associated with the keys 8 to l5 causes 8 annas to be entered into the anna Wheel. Depression of an anna key 8 to l5 also depresses the anna key 1 to '7 adjacent thereto. Thus, for example, if the 9 anna key is depressed, the 1 anna key is also depressed. Under this condition, the rack associated with the 9 anna key adds 8 into the anna totalizer, and the rack associated with the l anna key adds 1 into the anna totalizer a total of 9. Since no key is adjacent the 8 anna key, depression ofthe 8 key releases only the rack associated with the 8 to 15 keys to add 8 into the anna totalzer.

Therefore, to register 1 to '7 annas, the l to 7 rack is differentially moved under control of the 1 to 7 keys in one bank, and to register 9 to 15 annas, this same rack is moved from one to seven steps, and at the same time the 8 to 15 anna wheel is moved one step to add 8 annas, thus completing the proper registration. This is because each step of the 8 to 15 anna wheel is equal to 8 annas, so that each time the 8 to 15 annas totalizer wheel is moved one step, 8 annas are added into the totalzer.

The 8 annas key causes the 8 to 15 rack to move one step to add 8 on the 8 to 15 annas wheel. Thus, by using a 16-tooth 1 to '7 wheel with a 2-point standard transfer, and a 20tooth 8 to 15 Wheel with a l10--poir1t transfer, the proper annas of l to 15 can be accumulated and transferred into the rupee Wheel whenever 16 annas have been accumulated.

Should an overdraft occur, the regular overdraft mechanism used in machines of this type functions in its usual manner, for both registering and recording such overdraits, as is shown and described in the above-mentioned Christian Patent No. 2,038,717.

Now, in order to properly print the annas as they are registered, due to the fact that the printing members are set by the 1 to '7 and the 8 to 15 anna racks, it becomes necessary to supplement the movements of these racks by novel control or compensating devices controlled by these racks and the two banksof anna keys.

These same compensating devices function to control the printing of the annas under control of the two anna wheels when totals are printed from them.

In the description of the present invention, only so much of the standard-accounting machine will be described as is necessary to give a complete understanding of the invention and its working.

Operating mechanism The machine embodying the present invention is an accounting machine of the well-known Ellis type illustrated and described in the previously mentioned patents.

The machine may be operated by an electric motor of the conventional design shown in the United States patent to F. W. Bernau, No. 1,601,102, dated September 28, 1926, or the United States patent to Charles H. Arnold, N o. 2,142,341, dated January 3 1939.

Such a motor causes an oscillation or operating motion, first counter-clockwise and then clockwise, of a shaft 6I (Figs. 3, 4, and 8) as illustrated and described in the Christian, Bernau, and Arnold patents mentioned above. From this shaft 6I are derived the power and motion to operate the machine,

Framework The mechanism is supported by a framework including a base 62 (Figs. 3 and 14) having side frames 63 (only one being shown) which are connected by a cross frame 64 and tie bars 65 and 68.

The side frames 63 support a shaft 88 (Figs. 3 and 8), which is a part of the motor drive mentioned above; an aligner shaft 69; a printer drive shaft 18; and the operating shaft 6| described above.

Keyboard 'I'he keyboard is shown diagrammatically in Fig. 1 and consists of two rows of keys I5 and 'I6 to register pies; two rows of keys and 'I8 to register annas; and nine rows of keys 'I9 to register rupees. These keys control the registration and printing of any of the denominations above mentioned for the Indian currency. The usual motor release bar 88 is also shown in Fig. 1.

The only part of the keyboard which has been shown in detail is the two banks of anna keys 'I'I and |8. The rupees keys.'|9 are of standard construction, and the pies keys 'l5 and 16 are also of standard construction.

The construction of the annas keys 'Il and 'I8 is special and novel, and their control over the printing of the amount of annas is also very special and novel.

The annas keys Ti are mounted on the usual key plate 8|, the lower edge of which is slotted to straddle the tie bar 66 (Fig. 3) and the top edge of which contacts and is secured to the usual cover plate 82 (Fig. 1). Each of the keys 71 has a pin 83 (Fig. 3) cooperating with a zero stop control bar 84, which is supported by the plate 8| in the usual manner. A locking detent 85, partially shown, serves in the usual manner to lock down any depressed key TI, through the cooperation of a lug 86 and the pin 83.

Each key 'I'I also carries a square pin B'I (Figs. 11 and 12), which cooperates with a pin 88 on the key 'I8 directly opposite, as shown in Fig. 11.

Each key also carries the usual pin 89 to control the diiferential movement of an associated rack 98, held in its normal position by a zero stop pawl 9|. The rack 98 is guided by the tie bars 65 and 66. The pawl 9| engages a lug 92, and the upper end of the pawl is held in 6 contact with the bar 84 by a spring 93. The bar 84 is normally drawn to the right (Fig. 3) by a spring 94.

Depression of a key moves, through its pin 83, the bar 84 to the left, thus rocking the pawl 9| and releasing the rack 98, which is then moved to the right differentially under control of the pins 89, which cooperate with differential steps 95 of the rack 98 in the usual manner.

The rack 98 has a slot |88 engaged by a pin I8I of an operating lever |82 pivoted on the shaft 8|. A spring |83, connected to the lever |82, and a finger |84 on a bail |05 of a leading frame hold the lever |82 against the bail |85. This bail is carried by arms |86 (only one of which is shown) secured to the operating shaft 6|.

At the proper time after the key I'l is depressed, the shaft 6| is rocked counter-clockwise, as described above, whereupon the bail is moved to the right, the spring |83 rocks the lever |82, and the pin I8I moves the rack 98 until one of its shoulders contacts the pin 89 of the depressed key |'I. When the rack 98 stops, the continued movement of the bail |85 merely stretches the spring |83. Near the end of the operation, the shaft 8| moves the bail |85 back to normal position to restore the lever |82 and the rack 98 to their normal positions.

The rack 98 has the usual two sets of teeth I8'I for operating its associated totalizer wheels, to be described later.

An aligner |88, secured to the shaft 69, is operated in the usual manner to properly align the rack 98 and associated parts by engaging notches |89 in the lever |82.

The annas keys 'I8 (Figs. 8 and 11) are mounted on a key plate ||I slotted to embrace the tie bar 66. The plate III is also connected to the cover plate 82. Each key 18 has a pin I|3 cooperating with a zero stop control bar II4 mounted on the plate ||I. A locking detent II'5, partially shown, serves to lock down any depressed key 18, through its lug ||6 riding over the pin ||3. A pin I I9 on each key serves as a guide for the key, but in this bank it does not cooperate with the rack |28, since the rack, for reasons described later, receives only one step of movement regardless of which key 'I8 is depressed.

This rack |28 is held in normal position by a zero stop pawl I2 I, which engages a lug |22 of the rack |28. The upper end of the pawl is held in contact with the bar |I4 by a spring |23, and a spring |24 holds the bar H8 in the position shown until a key 'I8 is depressed, which moves the bar ||4 to free the pawl I2I from the rack |28. The rack |28 has a short notch |25, which allows the rack to move only one step when the pawl |2I is disengaged, the tie bar 86 acting as the limiting or stopping means for the rack. The steps |26 of the rack |28 do not control, as they do not Contact any of the pins I I9.

The rack |28 has a slot |38 engaged by a pin I3I of an operating lever |32 pivoted on the shaft 6|, and a spring |33 connected to the lever |32 and to the nger |84 of the leading frame bail |85 moves the lever |32 and the rack 28 one step each time one of the 8 to l5 annas keys 18 is de- Dressed.

In order to provide a good bearing for the lever |32, it has a bent arm |34 (Figs. 8 and 9), to which is secured an arm |35, which also bears on the shaft 6|.

The rack |28 has two sets of teeth |31 to cooperate with the annas wheels of the totalizers, to be described later. The aligner |88 cooper- '7 ates with notches |36 of the lever |32 to align the rack |29 and associated parts.

There is a rack |38 (Fig. 6) associated with and controlled by the two banks of pies keys 15 and 18. This one rack |38 is controlled by both banks of keys 15 and 1G. It is of the standard 12-division type for English currency, and, since 12 pies equal 1 anna, there need be no change in the rack for registering purposes in connection with the totalizer wheel and printing member to be described later.

There is also a standard -division rack |39' associated with each of the banks of rupees keys 19 for cooperating with the rupees Wheels of the totalizer and printer,

Totalieers There are two totalizers, numbered generally as |49 (Figs. 3, 4i, 5, 6, and 8). One is associated' with the lower sets of teeth on the racks 90, |20, |38, and |39, and one is associated with the upper sets of teeth on said racks. A part of one of said totalizers is shown diagrammatically in Fig. 6. These totalizers are adapted to be moved into engagement with the racks for adding, subtracting, sub-totaling, and totaling in the usual manner, as shown and described in the above-mentioned patents to Ellis, Christian, and Williams et al. Therefore the engaging and disengaging means has not been shown. Moreover, the carry or transfer mechanism has been only partially shown, since it is like that shown in said lastmentioned patents.

Since the currency being dealt with in` this case is the Indian currency, a brief description of the totalizer wheels and the transfer disks associated with the wheels will be given.

For the l to ll pies banks of keys 1'5 and 16', a 24-tcoth wheel |59 (Figs. 3, 4, and 6) is used. This wheel has a transfer disk |51 having two transfer points |52, so that, each time 12 pies are added into the wheel |59 by the rack |38, 1 is transferred into the lower order annas wheel The annas wheel E53 has 16 teeth and is actuated under control of the 1 to '7" annas keys 11 and the rack and has a transfer disk |54 with two transfer points |55, so that, each time 8 annas are added therein, the higher order annas wheel |55 is turned one step, Therefore, the construction of the totalizer wheels is such that each step of movement. of the annas wheel |56 is equal to the addition of 8 annas.

The annas wheel 5a has 20 teeth and a transfer disk |51 with ten transfer points |58, so that,

each time the wheel 58 is moved two steps, which equals 16 annas, the lower order rupees wheel |59 is turned one step to add 1- rupee. The wheel |55 also receives one step of movement by the rack |25 each time the machine is operated with one of the 8 to l5 annas keys depressed.

The rupees wheel |59 has 2() teeth and has a transfer disk |99 with two transfer points IGI, so that, for each 19 rupees added therein, 1 rupee is transferred to the next higher order rupee wheel |59 and so on upwardly for each of the successively higher order rupee Wheels. These wheels |59 are actuated, also, by the racks |39. under control of the rupees keys 19.

Thus, the pies wheel |59 is controlled by the pies keys and 13. The annas wheel 5371s controlled by the 1 to 7 annas keys 11 when any of those keys are operated alone. This wheel |53 is also controlled by the 9 to` 15 annas keys 18l to add various amounts from-1to13 because the 8 pins 88 of the 9 to 15 annas keys 18 overlie the pins 81 of the 1 to 7" annas keys, as shown ln Figs. 11 and 12; Therefore, should the 13 annas key 185 be depressed, it automatically depresses the 5 annas key 11, so that the Wheel |53 is turned to add 5 annas and the Wheel |56 is turned one step to add 8 annas', thus giving the total of 13 annas added according to the 13 annas key depressed.

The 9 key 18 and 1 key 11 add 8 on wheel |56 and 1 on wheel |53. The 15 key 18 and 7 key 11 add 8 on wheel |56 and 7 on wheel |53. The 8 annas key 18 has no key opposite it, so this 8 key adds 8 into wheel |56 by causing it to move one step, just as the 9 to 15 keys each cause one step of movement of wheel |56, which is the equivalent of adding 8 each time into this Wheel |56.

The complete transfer mechanism is shown in Ythe above-mentioned Ellis patents and in the- Williams et al. patent.

Printer The printing mechanism, as previously stated, is of the type used in the Well-'known Ellis machines having a traveling carriage. However, the invention is not in any way limited to a traveling carriage machine, because it will function exactly in the same manner if used in a machine with a non-travelingl carriage.

The particular problem involved herein, as stated at the outset of this case, is the control of the printing of the annas from the 1 to 1 annas keys 11 and from the 8 to 15 annas keys 18.

The printing of the pies from the 1 to 11 pies keys 15 and 16 is standard construction and need not be described in detail herein. Likewise the printing of the rupees from the rupees keys 19 is done in the regular Way. Also the printing of subtotals and totals from the totalizers requires no special manipulations on thepart of the operator, the pies and rupees type being set in the usual manner. However, the printing of the annas under control of the totalizer is also accomplished without any special manipulation onA the part of the operator, since the novel mechanism to be described automaticallyy controls the annas type members so that they will be properly set up forcorrect printing.

The only part of a carriage shown herein is a platen |19 (Figs. 3, 1,r 8, and-173), with which cooperate a pies type segment |1| (Fig. 5) having the characters l to l1; an annas type segment |12 (Figs. 3, 4, and 5) having the characters 0 to 9 specially arrangedy thereon as shown, with the 8 and 9 characters above the 0 character; another annas type segment |13 (Figs. 5, 8, and 13) having a single character 1; and nine rupees type segments |14 (Fig. 5) having the characters 0 to 9 arranged in the regular manner. Only three of' these segments |14 are shown in this case.

The annas segment |12 (Figs. 3 and 4) and its setting by the 1 to 7 annas keys 11 will be described rst. This segment is pivotally mounted on an operating arm |15, which is pivoted on the printershaft 10. A setting link |16 connects the segmentY |12 to a diierential-ly adjustable lever |11 pivoted on thershaft 6|; The lever |11 has an integral arm |18 havingY a slot |19 engaging a pin on a crank |8| pivoted at |82 on the previously described lever |-|)2,vwhich is set differentially. under control of the 1 to '1 annas keys`11 to s et the totalzer'rack 90.

The, crank |.8'| carries-another pin |83', which operates in a slot |84'of 'a lever |85 pvoted on a stud |86 of a bracket |81 secured to the frame 64 and a stud |88 in the base 62. The slot |84 is normally concentric with the shaft 6|, and consequently, when the lever |02 is diiTerentially adjusted from one to seven steps in the manner described previously, the arm |18, by means of the crank IBI and its pin |80, is driven along with the lever |02. In other words, the lever |02 and the arm |18 move as a single unit when adjusted under control of the 1 to 7 annas keys 11, and therefore the lever 11 and the link |18 differentially position the segment |12 from one to seven steps in a counter-clockwise direction to print the number of annas corresponding to the key 11 which has been depressed.

The arm |18 has aligning notches |89, with which the aligner |08 cooperates.

To operate the segment |12 to print the character set up, there are provided the usual driving arm I 90 (Fig. 3), actuating pawl |9I, and power spring |92. The arm |90 has the usual slot |93 engaging a pin |94 in the arm I 15. The pawl |9| is pivoted at |95 on the arm |15. The arm |90 is retained in normal position by a retaining finger I 98. Also the usual eliminating control lever |91 cooperates with the arm |90 and has a tail |98 with a notch |99, in which normally lies a pin 200 on the lever |11. The lever |91 is pivoted on a rod 20| carried by a printer bracket (not shown).

Pivoted on a rod 202 (Fig. 8) is a trigger 203 engaging the finger |96. The trigger 203 has a lip 204 carrying an adjustable screw 205 adapted to be contacted by a lever 206 (Fig. 3) secured to the printer shaft 10. The shaft 10 receives an oscillation from the motor-driven shaft 88, first clockwise and then counter-clockwise, as is fully shown in the Ellis and Williams et al. patents mentioned above.

When the lever |11 is moved counter-clockwise one to seven steps, the pin 200 rocks the lever 91 and disengages it from the arm |90. Then, when the lever 208 rocks the trigger 203 and releases the nger |96 from the arm |90, the spring |92 exerts its power on the pawl |9| to rock the arm |90 clockwise very rapidly, carrying the arm |15 and the segment |12 towards the platen |10 until the arm |90 strikes a stationary bar 201. Now, due to the slot |93 in the arm |90, the arm |15 and the segment 12 continue until the type on the segment strikes the paper around the platen |10, thus imprinting on the paper the selected character l to 7 under control of the 1 to 7 annaskeys 11.

After printing, a restoring rod 208, shown only in section and carried by arms secured to the shaft 10, restores the arms |90 and |15 and the segment |12, and a spring 209 rocks the lever |91 back into engaging position with the arm I 90. A spring 2|0 restores the trigger 203 and the retaining finger |96 to their engaging positions with the arm |90.

When there has been no key 11 depressed, the lever |11 will not move and the pin 200 does not release the lever I 91 from the arm |90, and consequently the segment cannot operate, notwithstanding the fact that the linger |98 has released from the arm |90. Therefore the will not be printed when there has been no key 11 depressed.

There is another control of the setting of the segment |12 from the 8 and .9 annas keys 18. It will be recalled that, when the 8 or 9 annas key 18 is depressed, the rack |20 (Figs. 3, 4, and 8) is controlled to move one step to the right. This step of movement controls the type segment |12, through means now to be described, to cause 8 10 or 9 to be Set up into printing position on the segment I 12.

The rack |20 (Figs. 3 and 14) carries a pin 2I| engaged by an arm 2|2 secured to a shaft 2|3 carried by a yoke 2| 4 formed on the bracket |81. Also secured to the shaft 2|3 is an arm 2|5 having a pin 2|8 projecting into a slot 2|1 of the lever |85. A spring 2|8 is used merely to take up lost motion in the linkages between the rack |20 and the arm |18.

When the 8 annas key 18 is depressed, the rack I 28 is moved one step to the right and rocks the arms 2|2 and 2|5 and the shaft 2|3 counterclockwise, which rocks the lever |85 clockwise, whereupon the crank |8| is rocked clockwise and the pin rocks the arm |18 clockwise, and its lever |11 lowers the link |16 and rocks the segment |12 two steps from 0 position into the 8 position, so that, when the 8 key 18 is depressed alone, 8 will be printed and 8 will be added into the totalizer by `movement of the Wheel |58 one step. The segment |12 is operated to print the 8 and is restored in the manner described above.

During this operation, the lever |02 and the rack 90 do not move, as they are held by the zero stop pawl 9|.

It might be well to state that a finger 2|9 on the lever |02 acts as a stop for the pin |80. The aligner |08 functions to engage the notches |09 and |89 of the lever |02 and the arm |18, respectively, to align the parts.

To print 9 when the 9 annas key 18 is depressed, the parts function as follows. Since the pin 88 on the 9 key 18 .overlies the pin 81 on the 1 key 11, this key 11 is automatically depressed, and consequently the lever |02 is moved one step to operate the rack 90 to add 1 in the annas wheel |53.

This one step of movement of the lever |02 in a counter-clockwise direction takes place while the arm |18 is being moved two steps in a clockwise direction, with the result that the lever |11 and the segment |12 receive an ultimate one step in a clockwise direction, which sets the "9 character on the segment |12 in position to print 9.

During the printing of the characters l to 9 from the segment |12, the segment |13 (Figs. 5, 8, and 13) has not been operated, due to means to be described later.

This segment |13 is operated to print whenever any of the 10 to 15 annas keys 18 are used to register any of those amounts. However, the segment |12 is also controlled by the "10 to 15 keys 18, and this will be first describedl Depression of the 10 key 18 causes an automatic depression of the "2 key 11, and therefore the lever |02 and the arm |18 are moved two steps counter-clockwise to set up the 2 character on the segment |12, but, since the rack |20 is moved one step to the right under control of the 10 key 18, the arms 2|2 and 2|5 and the lever rock the crank |8I clockwise to pull the arm 18 back two steps, thus resetting the segment |12 from the 2 printing position to the 0 printing position.

This moves the pin 200 (Fig. 3) back into the notch |99 and would prevent printing of the 0, but, since the 10 key 18 is depressed, it sets up a control, to be described later, whereby a lever 280 (Fig. 8) is rocked counter-clockwise, and this lever contacts a lip 23| (Fig. 3) on the lever |91 and releases it from the operating arm |90, so that the "0 will be printed by the segment |12 when the 10 annas key 18 is depressed.

Thus the 11 key 18 causes the segment |12 to print a 1; the "12 key 18 causes printing of a 2; the 13 key 18, a 3; the "14 key 18, a 4; and the l5 key 18, a 5, all from the segment |12.

An additional aligning device is provided for the lever |85 and associated parts. This aligning device is shown in Figs. 3,4, '7, and 14 and includes a lever 232 pivoted at 233 on a bracket 234 secured to the base 82. The lever 232 has notches 235 and 236 adapted. to engage a stud 231 on the lever |85. Normally an arm k238 of the lever 232 is held against a plate 239, rast to the bail |85 of the leading frame, by a spring 248.

If the lever |85 is not moved, then, when the bail passes from beneath the arm 238, the spring 248 rocks the lever 232 until the notch 235 engages the stud 231, thus holding the lever |85 and associated parts in proper positions until the bail |85 is returned to normal, during which return the arm 238 is contacted by the plate 239 and rocked clockwise to normal position, thus disenga'ging the notch 235 from the stud 231.

If the lever |85 has been moved as shown in Fig. 4, the notch 236 engages the stud 231 to properly align the lever |85 and associated parts.

The operation and control of the type segment |13 (Figs. 8 and 13) will now be described. The segment |13 is pivoted to an arm Y24| loose on the shaft 18. A link 242 connects the 'segment |13 to a lever 243 having a hub 244 journaled on the shaft 6|. The segment |13 has a single type l normally two steps of movement below the printing line position.

Also secured to the hub 244 is an arm 245 (Fig. 18) having a slotted nger 246, into which lprojects a pin 241 of a crank 248 pivoted at 249 on a plate 258 secured to the previously described lever |32 by studs 25| (see also Fig. 9). The crank 248 has another pin 252 normally held against the left side of a slot 253 in the plate 258 by a pin 254 on the crank 248 contacting a lever 255 pivoted on the stud |86. The lever 255 is held in the position shown in Fig. 8 by a pin 258 on a lever 251 pivoted on the shaft 2|3, which lever 251 has another pin 258 resting on a raised section 259 of a bar 268 secured to the side of the rack 98.

When the rack |28 is moved one step by the lever |32 upon depression of the 8 or "9 key 18, a spring 26|, connected to the lever |32 and the arm 245, rocks the arm 245 and the lever 243 one step, which raises the segment |13 one step, but, as this is a blank position, no printing takes place from the segment |13.

When the 9 key 18 is depressed, the rack 98 moves lone step. as previously described. but the raised section 259 is long enough so that the pin 258 holds the pin 252 against the left side of the slot 253.

However, when any of the 10 to 15 keys is depressed, the rack 98 moves from two to seven steps and the spring 26| then rocks the arm-245 counter-clockwise one step, as the pin 258 is permitted to move down onto the lower surface 262 of the bar 268. The pin 252 now is against the right side of the slot 253. Now, since the arm 245 and the lever 243 have been moved one step by the spring, due to the fact that the rack 98 has moved at least two steps, and since the lever |32 is moved one step caused by the depression of a 10 to l5 key 18, the arm 255 and the lever 243 also receive this additional step, thus moving the 1 on the segment |13 into printing line position. The arm 245 has aligning notches 263 to cooperate with the aligner |88.

Thus it can be seen that the 1 on the segment |13 is moved into position only when the rack 98 associated with the 1 to 7 keys 11 has moved at least two steps.

To operate the segment |13 to print, there is an arm 218 connected by a pin 21| and a slot 212 to the arm 24|. The arm 210 is operated by a pawl 213 and a spring 214 when the trigger 283 releases the linger |96 as described above.

However, there are certain non-print controls to be considered. The lever 238, pivoted on the rod 28|, has a tail 215 with a notch 216 cooperating with a pin 211 on the lever 243. This slot is long enough to prev-ent release of the lever 238 when the lever 243 is moved on`y one step, and also prevents release of the lever 238 when the lever 243 is not moved. Therefore; even though the trigger 283 releases the nger |96, the segment |13 will not print under these two conditions. However, when the lever 243 is moved two steps, the pin 211 acts on the tail 215 to release the lever 238 from the arm 218 to permit the segment |13 to be operated to print 1.9)

A spring 286 restores the lever -238 after printing has taken place.

In taking totals or sub-totals from the totalizers to print the amounts therein, the above-described compensating or type control mechanisms function to cause the type segments |12 and |13 to be properly setto print correct`y.

Specifically, if the annas Wheel |53 has any amount from 1 to 7 therein and if the annas wheel |56 has nothing therein, the segment 12 will be adjusted by the rack 98 to select the one ofthe characters l to 7 to print.

If the wheel |53 has an amount of 2 or abovefor example, G-and if the wheel |56 has l therein, the rack 98 will select the type character according to the amount therein-namely, 6- and the rack |28 will move one step, which represents 8. Since 6 plus 8 equals 14, the arm 178 is moved under control of the rack |28, and the type segment |12 is moved back two steps, from 6 to 4. At the same time, the segment |13 is moved one extra step by the arm 245 under control of the rack 98, so that the 1 is in printing position.

Therefore, 14 will be printed by the segments |13 and |12, which represents the total of 6 annas from the wheel |53 and 8 annas from the wheel |56.

In Fig. 2, there is shown one form of a card 312 which may be printed by the machine embodying this invention; In the debit and credit columns, the printing is done under control of the keys 15 to 19. In detail, the groups of figures marked 278 are printed by the rupees type segments |14 (Fig. 5); those marked 279, by the annas type segment |13; those marked 280, by the annas segment |12; and those marked 281 by the pies segment |1|..

In the balance column, the printing is done under control of the totaliZers. The group of ngures marked 282 is printed by the rupees type segments |14 under control of the rupees totalizer wheels |58; the figures marked 283 are printed by the annas type segment |13 under control of the annas totalizel1 wheel |56; the gures marked 284 are printed by the annas type segment |12 under control of the annas totaizer wheel |53; and the figures marked "285 are printed by the pies type segment I'll under control of the pies totalizer wheel |50.
